SPECIFICATION forming part of Letters Patent No. 629,186, dated July 18,189,9.

j 'd/ZZ wtmn t may concern: AA"',e it known that I, JOHN ARRAS, .I r., acitiof the United States, residing at St. Louis, the State of Missouri,have invented cerpi new and useful Improvements in ,Chaff-v v-faratorsVfor Threshing-Machines, of which s. following is a full, clear, andexact def'iption, reference being had to the accom- .,nying drawings,forming part oi' this speci- Afation. y

'Hy invention relates to an appliance for leshingmachines whereby thechaff may separated from the grain and straw and @ducted transversely ofthe machine to sep- .te Outlets from those at which the grainA l straware discharged from the machine. .'dy invention consists in features ofnovy hereinafter fully described, and pointed it in the claims. Figure Iis a view showing a portion of a :meshing-machine in side elevation,with a part of the side Wall broken out to illustrate ny appliancelocated therein, portions of the .iterior apparatus being shown insection. fig. II is an enlarged detail top View of a part at' thedeflector screen, plate, and iingers mounted therein. Fig. III is asectional view taken on line III III, Fig. II. Fig. IV -isfa sideelevation of the chaff-conveyer. Fig. V is a detail View of thecl1a-elevator-Operat lng mechanism.

1 designates the bodyof a threshing-ma- .l1ine, containing the usual fan2, through neans of which the chaff is blown from the .grain as it isdelivered from the cylinder of l he machine. y

3 is the usual shaker, located in therear of the machine-cylinder, fromwhich the grain falls into the endless carrier 4 and is delivered intothe shaker-screen 5.

My improvement relates solely to an appliance arranged transversely ofthe machine for removing the chaff from the machine through its ownindividual outlet, and I will therefore only describe such parts of themechanism as up the machine may be of any common con.- struction.

6 designates a deiiector-plate mounted over the innermost end of thecarrier 4. This plate is formed with a downturned end '7 and is ofreplacing any of the parts. 'screen 11 extends downwardly to a point 14,

and impart motion to the belt 25.

bent to form corrugations 8 on its upper side, the plate 6 containing a'transverse bar 9', mounted in which are rearwardly-projecting fingers10.

11 designates a screen provided with a crossbar 12, that is connected tothe plate 6 by hooks 13, the hooks being preferably movably joined tothe cross-bar 12 by bolts, so that the parts may he readily disconnectedas occasion may demand-such, for instance, as the necessity The deector-Where it is suitably secured. 1

15 designates uprights extending transversely of the threshing-machine,forming a guideway 16 between them. Mounted in these uprights are drums17 and 17, the shafts of which arek arranged in approximately the samehorizontal plane. The drums 17 and 17n receive an endless carrier 1S,that travels on Y them and is capable of being impelled in obverse orreverse directions.

19 designates a drive-shaftprovided with a pulley 20, located exteriorof the threshingmachine and adapted to receive a drive-belt, throughmeans of which the shaft 19 may be propelled. 0n the shaft 19 is abevel-pinion 2l, that meshes with a bevelpinion 22 on a shaft 23. TheOpposite end of the shaft 23 is provided with a pulley 24, that receivesa belt 25. The belt 25 extends from the pulley 24 to a pulley 26,mounted on lche shaft of the drum 17a. By this described mechanism theconveyer 18 is driven 'when power is applied to the drive-pulley toimpel the shaft 23 belt is arrangedon the pulleys 24.- and 26, as showninFig. IV, the conveyer 18 is caused `totravel in one direction, and thechaff in passing to said conveyer is blown against the delector-plate 6and deiector-screen 11 and is carried to one side of thethreshing-machine, While if the belt 25 be crossed the conveyer 1S willbe caused to travel in the Opposite directionand deliver the ch'aii atthe Opposite side of the machine. The fingers 10, located between thedeiectoi-plate 6 and the deilectOr-screen 11, are designed to permit thedescent of any grain that may be thrown beyond the end of the shaker 3,so that the said When the' IOO grain may fall into the shaker-screen 5,While at the saine timethese fingers prevent the descent of the strawthrough the chaff-separator.

I claim as. my inventionl. A threshing-machine comprising adelector-plate, a defiector-screen against which 4the chaff from thegrain is directed, and a conveyer arranged transversely of the machineonto which the chaff is deposited from said defiector plate and screen,and Where-b y it is discharged from the side of the machine;4substantially as described.
